Sierra and Time Machine

Hi.


So I upgraded to Sierra yesterday morning.


Time Machine has been stuck since.


It's stuck on 'Preparing Backup'.


It's been about 18 hours.


At what point should I worry? And suggestions on a fix?

Hi Don,


I solved my problem (see above)...

Perhaps that helps...


I noticed that in Console (typing "backupd" in the search box/"diagnoses and user-info") many lines with "backupd" in it.

In never saw this in previous OS X-versions - see also this question/thread of mine...How can I see Time Machine activity in Console with macOS Sierra.


Could it be that after updating to Sierra Time Machine is indexing the whole Time Machine-disk and this is the reason it takes forever?


It would be helpful to know what Time Machine is doing all this time...


A few years ago "pondini", who is king in solving Time Machine-troubles, was very active in "Apple Support Communities". He even has his own website concerning Time Machine... http://pondini.org

He did not update his website for a few years now...

His troubleshooting was very helpful to me then...


Were are the multilevel-experts?

reboot your Mac, - hold Command+R keys (till after the "boing-restart-sound" and you see the Apple-logo).

Wait for dialogue-box to appear.

Make sure your wifi is active, on the right above in menu-bar (it could be you need the password of your internet-modem)

Then install macOS Sierra again (you need to type in your Apple-ID with password).

This is the way you install on top of your existing macOS.

Sorry, -


...it seems you're stuck.

Hope you're not in a loop now...


You don't have an old TM-copy (recent date) to restore your whole iMac to the (old) previous state anymore?


Your profile states you're Mac was on Lion, - correct?.

It seems to me that upgrading from Lion to Sierra could be the problem.


If you had El Capitan (10.11) I don't understand why you only have the option to install Lion (10.07).


Succes Don.

About "mkdir") from macrumors/guides: http://guides.macrumors.com/mkdir


Strange that you mac creates a tmp-file (temporary file) on your desktop.

It seems something is seriously wrong - why does your Mac automatically create a directory by putting a file on your desktop? Strange...


Did you restore permissions on your harddisk and also TM-disk? - restart in recovery-mode by restarting using Command+R and then choosing Disk-repair and run it on those disks for best result.


If everything fails you could copy all of your important files to an external disk and go for a clean install...

I see no other solution.


I mailed "pondini" via his website a few hours ago...

He hasn't responded yet...

On his website he states: "I do not answer specific questions or problems via e-mail; only in the ASC forums",

- but I asked him anyway...

Hi “pondini”,


Hope all is well…


Now macOS Sierra has arrived some people have Time Machine-troubles.


see thread (example) https://discussions.apple.com/thread/7677444?answerId=30688752022#30688752022&start=0&tstart=0


Hope to see you back in the Apple-forums.

You’re surely missed.


Compliments for all you have done in the past.


Sorry for my poor English.


Best regards,
